Saudi Arabia wants to acquire Lockheed Martin AN/TPQ-53 counter-battery radar for border security requirements, to modernize its armed forces with a more current capability to locate and counter the source of incoming ballistic artillery, rockets, and mortars and enhance interoperability with the US and other allies.The US Defence Security Cooperation Agency notified Congress on the potential $662 million deal on 5 June, covering 26 radar systems, ammunition for live fire exercise, tools and test equipment, training, technical and logistics support. 

If the foreign military sales request receives approval, Saudi Arabia will become the first export customer of AN/TPQ-53.
